CTICasesPost-Lobectomy Unilateral Pulmonary Edema from Kinked Pulmonary Artery

Imaging findings
Post-right middle lobectomy and tracheal repair with muscle flap, chest radiographs and CT showed striking asymmetric edema in the unaffected left lung. The CT revealed kinking of the left pulmonary artery associated with the muscle flap, causing elevated left pulmonary arterial pressures.
Key takeaways
Asymmetric pulmonary edema can result from increased hydrostatic pressure in pulmonary arteries, even in the lung contralateral to the surgical site. Surgical revision of the muscle flap resolved the kinking and edema.
